To all whom 'it may concern.-

Be it known that I, EDWARD Rlvnr'r, a citizen of the United States,residing at Boston, in the county of Suflolk and State oi MasseBall-Bearings, of which the following description, in connection withthe accompany-- ing drawings, is a specification, iike numerals on thedrawings re resenting like 'parts.

This invention re ates to ball-bearings, and has for its object toprovide such a bearing with novel means for retaining the balls in theball-race.

' The features of the invention will be more fully hereinafter describedand then pointed out in' the claims. 7 In the drawings, Figure 1 isaside elevation of the essential elements'oi" a hall-hearing, showing myinvention epplied thereto. 20 2 is e section on the lines :22, Fig. I.Fig.

he -ball-bearing"herein illustrated oomrises the two annular members 3end each liaving a. bail-race 5 therein, in whiehithe balls 6 maytravel. -Either the member 3 or the member-'4 may be the rot member. The

member 3 is shown ashavmga. bell-supply groove 7 loading from the sideface 8 thereof parallel to the axis of rotation and terminate mg at thebell-race. The inner extremiti oi the; roovc is substen i ally at thecenter 'ne 4 of t e ball-race, although in practice it will be necessaryto make it extend sufficiently sorted. This bell-supply groove isnormall closed by a bell-retaining key 9, which fi s the move and hasits inner end 10 shaped to confi m to the ball-race, end its outer end 11 flush with the side 8 of the member-3. The ball-retainingvkey 9 ismade'removahle, end when it is removed the bells 6 may be readilydropped into the race through thehell-suppl "ove 7 the balls astheyenter the race one ein moved iaterally therein to make room for t jenext'bell. .The'pl otthe hails in. the race is accomplished, w esthe twomembers'3 and 4 are iii-proper relative tion. After the balls areinserted the mretaining key 9 is placed in the hall-supply groove 7therebg to hold the balls in place. To prevent t v e key from becomingdiechusetts', have invented an Improvement in" a'deteil view showing themanner of re- 7 s ctive view of the be -retaining kevmnd below thecenter to permit the balls to be ill-- the groove=13 in said he an madeas small as balls to be readily inserted into the ball-race.

, bee

lodgedylfernploy s. spring-ring 12 which occupiesan annular groove 13the inner face of the bearing member 3, said groove being "situatedsuficiently above the ball-race so that the ring 12 wiil not interferewith the operation of the balls. The spring-ring also enters a groove 14in the inner es of the ball-retaining key 9, and thereby ocks the. keyin lace. In order to permit the resdy remove of said s ring-ring in caseit is de.

sized to remove t e key 9, I have provided said key with a groove orrecess 15, extend 'ingtrensversely to the groove 14, in which .grooveifi the pointed end of an implement 166 may be inserted to prythesspring-ring onti of its seat. The ends "of the ring are preferablyundercut as shown at 15, so that the ring may he piolred out of itsgroove-by inserting the pointed end of an implement nndemeeth'either oneof the nnderent ends of seid-ring',

k In making the above invention-my object has been to provide a;construction in which the minimum amount of material is removed intheforming of the hall-suppjy groove or the groovefor receiving theall-retaining key, and also to provide a. construction for retaining thekey in-pleee which does not in any we? weaken either of the beering"memhers. t willbe noted that the bell-supply groove 7 extends onlypartially throughithe caring member 3 and that the {presence of 3 doesnot Thehslkstipp ygroove 7 is possible an yet permit the Weaken itFurthermore, both the bell-retaining key and the means for holding. saidkey in place are ioeated within the bearingend none ofthesepartsrgroject beyond the faces of the 's makes a construction whichis especially edep'tedi'or use in automobiles end other places where aball-bearin meximurn strength but ,occup mum space is desired, One oi tof a minie advantages of this'construction is that when the bear-inmember is rotati ra idly the centrifuga force tends to mor e firnil ysent the ring 12 in its groove. I

Hevi fniiy described my invention, what I claim as new, and desire tosecure by Letters Iatent' is.

1. In a hall-bearing an hes member having an'interior annular bail-33%and a halbsu ply groove extending parallel to the axis 0 rotation and'leedingio said ros ball-raee, a ball-retaining key removably sustainedin said groove, and a spring-ring occupying an annular groove in thelnterior groove on thejnner face of the key, said key aving animplement-receiving groove ex- 15 tending transversely to the spring-rint0 afof the bearing member and seated in a trans- 1 ford means for theinsertion of an implement verse 1groove on the inner face of the key.

2. n a ballbearing, an annular bearing member having an interior annularball-race and a ball-su ply groove extending parallel to the axis 0rotation and leading to said 1 o ball-race, a ball-retaining keyremovably sustained in said oove, and a spring-ring occu- Eying an annuar groove in the interior of the earmg member and seated in a transversebehind said ring for removing the latter.

In testimony whereof Ihave signed my name to this specification in thepresence of 20 two subscribing witnesses EDWARD RIVETT.
